She's the most powerful woman in Congress, and they call themselves the "largest black female organization in the universe." They agree on progressive issues from voting rights to fair wage legislation and on the national implications of what are often dismissed as women's concerns. It's no surprise that House Minority Leader Nancy Pelosi (D-Calif.) and members of Delta Sigma Theta Sorority Inc. hit it off.

On Tuesday, DST National President Paulette Walker, along with members of the sorority's executive committee and representatives of California chapters, met with Pelosi in her Washington, D.C., office. The event was among the last of the group's annual Delta Days in the Nation's Capital, a legislative conference designed to increase members' involvement in national politics.

Pelosi used the meeting primarily to tout the House Democrats' economic agenda for women and families, a set of policy priorities that includes increase in minimum wage, equal pay for women, affordable child care and paid leave, asking her guests to be part of the "drumbeat" of public support for it. It didn't take much convincing. After all, Walker told The Root, the beliefs behind the agenda's motto, "When women succeeds, America succeeds," are nothing new to the members of the 101-year-old, service-based organization.

"Unless we address issues related to education and the women's economic agenda, we'll be perpetuating a disparity," Pelosi told the 23 members of Delta Sigma Theta gathered in her Capitol office. She reminded the group that "When women succeed, America succeeds" was the biggest applause line of the night at President Obama's recent State of Union address. (It got another round from the women sitting around the conference table.)

"We're so proud of the Deltas in the Congress," Pelosi said, adding, "I was told not to wear red today because I'm not a Delta."

She may not have worn the group's signature color, but a light moment came when Pelosi addressed Walker as "Soror Walker," embracing an honorific that's typically used only among members. If rules were violated, the minority leader got a pass—and more applause.

Reps. Yvette Clarke (D-N.Y.) and Joyce Beatty (D-Ohio), also members of Delta Sigma Theta, joined the group. "This is to the heart of who we are as Deltas," Clarke said of the women's economic agenda. "Part of what we're trying to do here in the House of Representatives is to raise the stature of women to counteracting and counterbalance the negative imagery that is being portrayed by the other side of the aisle."

DST National Social Action Commissioner Leona Bridges listed additional legislative interests of the organization, including the implementation of the Affordable Care Act, the passage of the Voting Rights Amendment of 2014 and efforts to reduce gun violence.

On the importance of protecting voting rights, Pelosi agreed, emphasizing, "Voter ID is nonmenacing to the public so people don't think that's a big deal, but it's a very big deal. But the speaker of the House in Texas is 90 years old; he was turned away at the polls because his driver's license expired."

"It's significant that we're sitting at the table. This means we've come together to join forces to say our ideas, vision and mission are the same. We are so pleased that you [Pelosi] also recognize, acknowledge and affirm our work," Walker said.

When it comes to legislation, "Public sentiment is everything," said Pelosi. "So we need your help with that drumbeat."

"We're going to answer your calls. Social action is our agenda," said Walker. Later, she told The Root, "The very next step is to go back home, look at all the notes, and put together a strategic plan. This wasn't just a feel-good moment. Now we're about to roll up our sleeves and do the real work. We will mobilize to help pass key legislation. We will be heard in the right places."

"We'll be strategically thinking about the midterm elections," Leona Bridges added. "Making sure people get out and vote, don't go to sleep. Making sure people know how important it is to vote."

"The meeting was monumental, it was historic. This country will go as women go. If anyone's going to lead the women, it might as well be us," said Walker. "All leader Pelosi needs to do is make a phone call, and we can mobilize and do what we need to do."
